# Docker Compose Examples for Testing Health Status Aggregation
|
||||
|
||||
These example docker-compose files demonstrate different container health status scenarios to test the "unknown" health state aggregation fix.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
```bash
|
||||
# Make sure Docker is running
|
||||
docker --version
|
||||
```
|
||||
|
||||
## Test Cases
|
||||
|
||||
### 1. **Healthy** - All containers with passing health checks
|
||||
|
||||
**File:** `docker-compose.healthy.yml`
|
||||
|
||||
```bash
|
||||
docker-compose -f docker-compose.healthy.yml up -d
|
||||
docker-compose -f docker-compose.healthy.yml ps
|
||||
docker inspect $(docker-compose -f docker-compose.healthy.yml ps -q web) | grep -A 5 '"Health"'
|
||||
```
|
||||
|
||||
**Expected Status:** `running (healthy)`
|
||||
- Container has healthcheck that successfully connects to nginx on port 80
|
||||
|
||||
**Cleanup:**
|
||||
```bash
|
||||
docker-compose -f docker-compose.healthy.yml down
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. **Unknown** - Container without health check
|
||||
|
||||
**File:** `docker-compose.unknown.yml`
|
||||
|
||||
```bash
|
||||
docker-compose -f docker-compose.unknown.yml up -d
|
||||
docker-compose -f docker-compose.unknown.yml ps
|
||||
docker inspect $(docker-compose -f docker-compose.unknown.yml ps -q web) | grep -A 5 '"Health"'
|
||||
```
|
||||
|
||||
**Expected Status:** `running (unknown)`
|
||||
- Container has NO healthcheck defined
|
||||
- `State.Health` key is missing from Docker inspect output
|
||||
|
||||
**Cleanup:**
|
||||
```bash
|
||||
docker-compose -f docker-compose.unknown.yml down
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 3. **Unhealthy** - Container with failing health check
|
||||
|
||||
**File:** `docker-compose.unhealthy.yml`
|
||||
|
||||
```bash
|
||||
docker-compose -f docker-compose.unhealthy.yml up -d
|
||||
# Wait 30 seconds for health check to fail
|
||||
sleep 30
|
||||
docker-compose -f docker-compose.unhealthy.yml ps
|
||||
docker inspect $(docker-compose -f docker-compose.unhealthy.yml ps -q web) | grep -A 5 '"Health"'
|
||||
```
|
||||
|
||||
**Expected Status:** `running (unhealthy)`
|
||||
- Container has healthcheck that tries to connect to port 9999 (which doesn't exist)
|
||||
- Health check will fail after retries
|
||||
|
||||
**Cleanup:**
|
||||
```bash
|
||||
docker-compose -f docker-compose.unhealthy.yml down
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 4. **Mixed: Healthy + Unknown** → Should show "unknown"
|
||||
|
||||
**File:** `docker-compose.mixed-healthy-unknown.yml`
|
||||
|
||||
```bash
|
||||
docker-compose -f docker-compose.mixed-healthy-unknown.yml up -d
|
||||
docker-compose -f docker-compose.mixed-healthy-unknown.yml ps
|
||||
docker inspect $(docker-compose -f docker-compose.mixed-healthy-unknown.yml ps -q web) | grep -A 5 '"Health"'
|
||||
docker inspect $(docker-compose -f docker-compose.mixed-healthy-unknown.yml ps -q worker) | grep -A 5 '"Health"'
|
||||
```
|
||||
|
||||
**Expected Aggregated Status:** `running (unknown)` ← **This is the fix!**
|
||||
- `web` container: `running (healthy)` - has passing healthcheck
|
||||
- `worker` container: `running (unknown)` - no healthcheck
|
||||
- **Before fix:** Would show `running (healthy)` ❌
|
||||
- **After fix:** Shows `running (unknown)` ✅
|
||||
|
||||
**Cleanup:**
|
||||
```bash
|
||||
docker-compose -f docker-compose.mixed-healthy-unknown.yml down
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 5. **Mixed: Unhealthy + Unknown** → Should show "unhealthy"
|
||||
|
||||
**File:** `docker-compose.mixed-unhealthy-unknown.yml`
|
||||
|
||||
```bash
|
||||
docker-compose -f docker-compose.mixed-unhealthy-unknown.yml up -d
|
||||
# Wait 30 seconds for health check to fail
|
||||
sleep 30
|
||||
docker-compose -f docker-compose.mixed-unhealthy-unknown.yml ps
|
||||
docker inspect $(docker-compose -f docker-compose.mixed-unhealthy-unknown.yml ps -q web) | grep -A 5 '"Health"'
|
||||
docker inspect $(docker-compose -f docker-compose.mixed-unhealthy-unknown.yml ps -q worker) | grep -A 5 '"Health"'
|
||||
```
|
||||
|
||||
**Expected Aggregated Status:** `running (unhealthy)`
|
||||
- `web` container: `running (unhealthy)` - failing healthcheck
|
||||
- `worker` container: `running (unknown)` - no healthcheck
|
||||
- Unhealthy takes priority over unknown
|
||||
|
||||
**Cleanup:**
|
||||
```bash
|
||||
docker-compose -f docker-compose.mixed-unhealthy-unknown.yml down
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 6. **Excluded Container** - Unhealthy container excluded from health checks
|
||||
|
||||
**File:** `docker-compose.excluded.yml`
|
||||
|
||||
```bash
|
||||
docker-compose -f docker-compose.excluded.yml up -d
|
||||
# Wait 30 seconds for health check to fail
|
||||
sleep 30
|
||||
docker-compose -f docker-compose.excluded.yml ps
|
||||
docker inspect $(docker-compose -f docker-compose.excluded.yml ps -q web) | grep -A 5 '"Health"'
|
||||
docker inspect $(docker-compose -f docker-compose.excluded.yml ps -q backup) | grep -A 5 '"Health"'
|
||||
```
|
||||
|
||||
**Expected Aggregated Status:** `running (healthy)`
|
||||
- `web` container: `running (healthy)` - passing healthcheck
|
||||
- `backup` container: `running (unhealthy)` - but has `exclude_from_hc: true`
|
||||
- Excluded containers don't affect aggregation
|
||||
|
||||
**Cleanup:**
|
||||
```bash
|
||||
docker-compose -f docker-compose.excluded.yml down
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Quick Test All Cases
|
||||
|
||||
```bash
|
||||
# Test healthy
|
||||
echo "=== Testing HEALTHY ==="
|
||||
docker-compose -f docker-compose.healthy.yml up -d && sleep 15
|
||||
docker inspect $(docker-compose -f docker-compose.healthy.yml ps -q web) --format='{{.State.Status}} ({{if .State.Health}}{{.State.Health.Status}}{{else}}unknown{{end}})'
|
||||
docker-compose -f docker-compose.healthy.yml down
|
||||
|
||||
# Test unknown
|
||||
echo -e "\n=== Testing UNKNOWN ==="
|
||||
docker-compose -f docker-compose.unknown.yml up -d && sleep 5
|
||||
docker inspect $(docker-compose -f docker-compose.unknown.yml ps -q web) --format='{{.State.Status}} ({{if .State.Health}}{{.State.Health.Status}}{{else}}unknown{{end}})'
|
||||
docker-compose -f docker-compose.unknown.yml down
|
||||
|
||||
# Test unhealthy
|
||||
echo -e "\n=== Testing UNHEALTHY ==="
|
||||
docker-compose -f docker-compose.unhealthy.yml up -d && sleep 35
|
||||
docker inspect $(docker-compose -f docker-compose.unhealthy.yml ps -q web) --format='{{.State.Status}} ({{if .State.Health}}{{.State.Health.Status}}{{else}}unknown{{end}})'
|
||||
docker-compose -f docker-compose.unhealthy.yml down
|
||||
|
||||
# Test mixed healthy + unknown
|
||||
echo -e "\n=== Testing MIXED HEALTHY + UNKNOWN ==="
|
||||
docker-compose -f docker-compose.mixed-healthy-unknown.yml up -d && sleep 15
|
||||
echo "Web: $(docker inspect $(docker-compose -f docker-compose.mixed-healthy-unknown.yml ps -q web) --format='{{.State.Status}} ({{if .State.Health}}{{.State.Health.Status}}{{else}}unknown{{end}})')"
|
||||
echo "Worker: $(docker inspect $(docker-compose -f docker-compose.mixed-healthy-unknown.yml ps -q worker) --format='{{.State.Status}} ({{if .State.Health}}{{.State.Health.Status}}{{else}}unknown{{end}})')"
|
||||
echo "Expected Aggregated: running (unknown)"
|
||||
docker-compose -f docker-compose.mixed-healthy-unknown.yml down
|
||||
|
||||
# Cleanup all
|
||||
echo -e "\n=== Cleaning up ==="
|
||||
docker-compose -f docker-compose.healthy.yml down 2>/dev/null
|
||||
docker-compose -f docker-compose.unknown.yml down 2>/dev/null
|
||||
docker-compose -f docker-compose.unhealthy.yml down 2>/dev/null
|
||||
docker-compose -f docker-compose.mixed-healthy-unknown.yml down 2>/dev/null
|
||||
docker-compose -f docker-compose.mixed-unhealthy-unknown.yml down 2>/dev/null
|
||||
docker-compose -f docker-compose.excluded.yml down 2>/dev/null
|
||||
```
|
||||
|
||||
## Understanding the Output
|
||||
|
||||
### Docker Inspect Health Status
|
||||
```json
|
||||
"Health": {
|
||||
"Status": "healthy", // or "unhealthy", "starting"
|
||||
"FailingStreak": 0,
|
||||
"Log": [...]
|
||||
}
|
||||
```
|
||||
|
||||
If `"Health"` key is missing → Container has no healthcheck → Shows as `unknown`
|
||||
|
||||
### Coolify Status Format
|
||||
Individual containers: `"<status> (<health>)"`
|
||||
- `"running (healthy)"` - Container running with passing healthcheck
|
||||
- `"running (unhealthy)"` - Container running with failing healthcheck
|
||||
- `"running (unknown)"` - Container running with no healthcheck
|
||||
- `"running (starting)"` - Container running, healthcheck in initial grace period
|
||||
|
||||
### Aggregation Priority (after fix)
|
||||
1. **Unhealthy** (highest) - If ANY container is unhealthy
|
||||
2. **Unknown** (medium) - If no unhealthy, but ≥1 has no healthcheck
|
||||
3. **Healthy** (lowest) - Only when ALL containers explicitly healthy
